TOILET YENTILATOR Filed Nov. 6, 1951 Patented Oct. 17, 1933 UNITED STATES PATENT OFFICE TOILET VENTILATOR Harry Baither, Milwaukee, Wis.

Application November 6, 1931. Serial No. 573,475 1' claim. (c1. 4-213) This invention relates to improvements in toilet ventilators.

One of the objects of the invention is the provision of improved means for Ventilating a toilet 5 bowl by withdrawing the odors from the bowl during and directly after use, and directing these odors into the outlet to the sewer, so as to reduce to a minimum the possible chances of the odors escaping into the room in which the toilet is located.

Another object of the present invention is the provision of improved means for Ventilating toilet bowls which includes a suction fan operated by an electric motor controlled by means of suitable mechanism, such as disclosed in my pending application for toilet ventilators, Serial #428,337, filed February 14th, 1930.

A further object of the present invention is the provision of an improved toilet bowl ventilator, having a conduit leading from the body of the bowl to the outlet of the sewer with a blower fan therein todirect the odors from the bowl into the outlet, together with suitable means connected with the conduit to provide a seal therein which will prevent the return of the odors from this outlet to the bowl.

With the above and other objects in view, the invention consists in the novel features of construction, the combination and-arrangement of parts hereinafter more fully set forth, pointed out in the claim and shown in the accompanying drawing wherein:

Figure 1 is a sectional view of a toilet bowl, illustrating the application of my improved ventilator with parts of the same illustrated in elevation; and,

Figure 2 is a view similar to Figure 1, illustrating a slightly modified form of the invention.

Referring to the drawing, 1 indicates a body of an ordinary type of toilet `bowl having the usual annular water chamber 2 at Vthe top which has communication with the interior of the bowl by means of a plurality of apertures 3. The water chamber 2 is connected up with the main conduit 4 which leads to the ush tank 5 and a passage 6 communicates directly with the supply conduit 4.

My improved Ventilating mechanism includes a casing 7 in which a suitable type of electric 5o motor is arranged to operate a fan 8 in the housing 9. The housing 9 is connected up with the f interior of the bowl 1 by means of a pipe 10 which opens into the bowl 1 at a point directly below the upper edge thereof, as shown in Figure 1.

Leading from the other side of the housing 9 is a discharge conduit 11 having a goose-neck 12 therein, with one terminal of the goose-neck provided with a nozzle 13 adapted to be extended through one wall of the outlet 14. The nozzle 13 is retained in positionby means of a packing 50 end of which is curved inwardly toward the bowl 1, as shown at 17 and is provided with a tapered end 18 adapted to fit within a small opening in the bottom of the goose-neck 12. The tapered end 18 is provided with a restricted opening, as illustrated for supplying water to the goose neck 12 to form a seal therein when the device is not in use, so that the odors will not pass upwardly and return to the bowl 1.`

In the operation of the device, it is so arranged at the time the bowl is in use and for a short period thereafter, and while the air is being sucked from the interior of the bowl 1 and driven out through the conduit 11, the water in the goose-neck 12 will be forced outwardly and only a. small amount of water will seep in through the opening in the tapered end 18 of conduit 16, which will be quickly carried out bythe force of the blast from the fan 8. However, as soon as the fan ceases operation, the water in the conduit 16 will move through the restricted opening in the tapered end 18 and fill up the goose-neck 12, as shown in Figure 1, in order to provide a positive seal in the conduit 11 to prevent the odors from escaping upwardly from the outlet into the bowl 1.

The conduit 16 will be supplied with water 90 during the time the bowl is being flushed, as some of the water passing through the supply pipe 4 will run down into the conduit 11 and provide a sucient supply for sealing the gooseneck as described above. 95

In Figure 2, I have illustrated a slightly modified form of the invention wherein the conduit 10 is connected up direct to thewater supply pipe 4 and in this manner, the odors will be drawn upwardly through the apertures 3 in the chamber 2' and will be drawn off through the conduit 10 to the housing or chamber 9.

Further attention is directed to the fact that the conduit 11 in this construction is provided with the usual goose-neck 12', but instead of passing through one wall of the main conduit of the bowl 1', the conduit 11' is provided with an angular extension 20, the lateral portion of which extends through an opening in the discharge pipe .21, thus. relieving the necessity of drilling the bowl of the outlet 14 to insert the nozzle therein.

In this construction, a packing gland 22 is also used for retaining the nozzle in position. The modified form illustrated in Figure 2 also includes a water supply conduit 16' which leads downwardly from the main water supply pipe 4 and connected up with the goose-neck 12' in the same manner as described in the preferred form of the invention.

In the modified form of the invention, the operation is the same as in the preferred form, but instead of taking the odors direct from the body of the bowl 1', the odors are removed through the Water chamber 2 and the Water supply pipe 4 and instead of extending a nozzlev into the main outlet of the bowl, the discharge conduit is extended downwardly and coupled up with the discharge pipe which is connected to the outlet of the bowl. This latter construction in a great many instances will save considerable expense in installing the apparatus.

It will be apparent from the foregoing that I have provided a simple and inexpensive method for Ventilating toilet bowls to reduce to a minimum the possible escaping of the odors into the room in which the bowl is located, and wherein the odors will be readily carried off and directed into the sewer outlet, thus providing a very eilicient and sanitary device.

While I have shown and described'the preferred embodiment of my invention, it. will be apparent from the foregoing that slight changes may be made in the construction when putting the invention into practice without departing from the spirit of the same or the scope of the appended claim.

I claim:

A toilet bowl having an outlet, a water chamber around the upper edge of the bowl, apertures leading into the body of the bowl, a water supply pipe communicating with the chamber, a conduit having one end connected with the interior of the bowl below the upper edge thereof, a second conduit having connection with the first conduit and leading into the outlet, a goose-neck in the second conduit, a pipe having one end connected with the water supply inlet and the other end connected with the goose-neck and formed with a restricted opening to supply water to the gooseneck for forming a Water seal and amotor-operated fan for creating a draft in one of said conduits.
